DRAFT-GEAR FOR AGRICULTURAL MACHINES.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed September 3. 1906. Serial No. 333,783.

To all whom itma/y concern.-

Be it known that I, JABEZ TILLY, farmer, a subject of the King of GreatBritain and Ireland, resident of-Ladysmith, Kilkerran, State of SouthAustralia, Commonwealth of Australia, have invented a certain new anduseful Improved Draft-Gear for Strippers and Stripper HarvestingMachines and Similar Agricultural Machines, of which the following is aspecification.

This invention has been designed especially to lessen the side draft ofa stripper or stripper harvesting-machine, thereby enabling a greaternumber of horses to be at tached abreast without walking in .the crop.It may be applied also to any other agricultural machine having a bodywhich is oscillated upon the main axle and draft attached to a platformat one side of the oscillating body.

My invention consists in improved draft attachments or connections andcomprises an arc-shaped loop attached to the near side of themachine-body-toward the front, carrying a roller and shackle attached bya suitable connection to one end of the hinder of two draft-bars,suitably connected to one another and to the platform of the machine.

In order that my invention may be clearly understood, I will describethe same with reference to the accompanying drawings, in

which so much only of the machine is shown as is necessary to clearlyillustrate my invention.

Figure 1 is a plan view indicating in outline only the general shape ofthe forward portion of an ordinary stripper. Fig. 2 is a side view whichshows the oscillatable body only of the machine with the arc-shaped loopand the roller-gear. The platform and swings are removed.

This device may be constructed of any de sired strength and the relativelengths of the swings and connections adjusted accordingto the size ofthe machine upon which it is to be used.

A is an arc-shaped loop attached by means of its stem B to the near sideof the machinebody, preferably to the bottom beam of the machine, asshown. The arc-shaped portions of the loop are concentric with the axleof the machine. The top of the arc-shaped loop is connected by a stay Cto some convenient part of the machine.

Within the arc-shaped loop is a roller D (which cannot be seen in Fig.1.) with a shackle E, which shackle extends across the front and rearmembers of the loop, its front end having an eye whereby it is connectedby a chain 'F to the off end of the rear draftbar H. The stem B has anoutward set, so that the roller and shackle may move up and down theloop clear of the machine-cheek. The near end of the rear draft-bar H isconnected by a clip J to a beam K, extending forward and outward fromthe near side of the platform. It rests near its other end upon a beamL, projecting out from the off side of the platform. The front draft-barM is connected at its off end by means of a clip N to the rear draft-barH. The point of attachment is varied as desired. The near end of thefront draft-bar M is connected by a chain P to the rear of the near sideof the platform. Both of the draft-bars have a number of holes, so thatthe position of the several attachments may be altered to adjust thedraft.

Near the front of the platform on its near side is an outrigger-beam R,hung on a vertical pivot having at its outer end a short chain S, whichsupports the main chain P and also the near end of the front draft barwhen turning. The vertical pivot allows the beam R to fold backwardtoward the platform when the team is swinging round at the end of thefield.

Having now fully described and ascertained my said invention and themanner in which it is to be performed, I declare that what I claim is 1.Improved draft gear, comprising an arc-shaped loop attached to the nearside of the machine-body toward the front and carrying a roller andshackle attached by a suitable connection to the off end of the reardraft-bar, the near end of such draft-bar being connected to a beamextending forward and outward from the near side of themachine-platform, such rear draft-bar being connected by a clip to theoff end of a front draft-bar the near end of which is connected by achain to the rear of the near side of the platform, substantially asdescribed and for the purpose set forth.

2. Improved draft -gear, comprising an the machine-body toward the frontand carrying a roller and shackle, in combination arc-shaped loopattached to the near side of with front and rear draft-bars and suitableconnections, such connections comprising a chain connection between thefront of the shackle and the off end of the rear draft-bar, a clipconnection between the near end of the rear draft-bar and a beamextending forward and outward from the near side of themachine-platform, a clip connection between the rear draftbar and theoff end of the front draft-bar, and a chainconnection between the nearend of the front draft-bar and the rear of the near side of theplatform, substantially as described.

3. In a draft-gear, an arc-shaped loop at tached to the near side of themachine-body toward the front, preferably to the bottom beam of themachine, and a roller and shackle carried by such loop the front end ofthe shacklebeing connected to a draft-bar the other end of which isconnected to the machine platform, substantially as described and forthe purpose set forth.

4. In a draft-gear of the kind described, an outrigger-beam hung on avertical pivot near the front of the near side of the platform, and ashort chain or connection between the outer end of the beam and the mainchain connecting the off end of the front draft-bar to the rear of theplatform, substantially as described and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname, in the presence of two subscribing witnesses, this 31st day ofJuly, 1906.
